Why is it, do you suppose, that Darwinist commenters ignore the evidence that life cannot form on it's own, that matter cannot form on it's own, that information only comes from intelligent sources and that the sedimentary rocks do not support uniformitarianism and the fossil record is not a sequential story of evolution but rather a testament to a world-changing flood event? Because they cannot actually fight on the field of evidence. Evolution is a series of fairy tales connected with assumptions and unsupported assertions that live best at the edge of evidence where science is still considering the implications. Maybe we should call this the "Piltdown Man Syndrome?" Darwinists depend on ignorance of the public to promote their point of view and yet even at that the public still has problems swallowing the Darwinian tale. So Darwinists must continually find new canards to promote. Thus, ERVs are the special of the day because we are still learning about them and Darwinists can make up stories about them that have not yet been entirely refuted. Or have they?

We will take a series on understanding the design of life out of order to immediately address the Darwinist canard concerning ERVs:

The inheritance of traits is determined by genes: long stretches of DNA that are passed down from generation to generation. Usually, genes consist of a coding part and a non-coding regulatory part. The coding part of the gene determines the functional output, whereas the non-coding portion contains switches and units that determine when, where and how much of the functional output should be generated. Point-mutations in the coding part are predominantly neutral or slightly detrimental genetic noise that accumulates in the genome, whereas point-mutations in the regulatory part of DNA units can induce variation with respect to the amount of output. Previously, in part 2, I argued that created kinds were frontloaded with baranomes: that is, pluripotent genomes with an ability to induce variation from within. The output of (morpho)genetic algorithms present in the baranome can readily be modulated by variation-inducing genetic elements (VIGEs). VIGEs are frontloaded genetic elements normally referred to as endogenous retroviruses, insertion sequences, LINEs, SINEs, micro-satellites, transposons, insertion sequences, and the like. In the present report, these transposable and repetitive DNA sequences are redefined as VIGEs, which solves the RNA virus paradox. The (morpho)genetic algorithms were designed in such way that VIGEs easily integrated into it and became a part of it, hence making the program explicit.

The variation that Darwin saw in pigeons can be explained with the activation or deactivation of existing genetic sequences for feather production in different parts of the body. This gives no basis for asserting that pigeons could change into something which is not a pigeon.

In order to fight off invading bugs and parasites, higher organisms have an elaborate mechanism that induces variation in immunological defence systems. One particular type of immune cells (B cells) produces defence proteins known as immunoglobulins. Immunoglobulins are very sticky; they bind to intruders as biological tags and mark them as ‘alien’. Other cells of the immune system then recognize the intruder, and a destruction cascade is activated. To have a tag available for every possible alien intruder, millions of B cells have their own highly specific gene for immunoglobulin production. In the genome there is only limited storage space for biological information, so how can there be millions of genes? Well, there aren’t. Immunoglobulin genes are assembled from several pre-existing DNA sequences that can be independently put together. The part of the immunoglobulin that does the ‘alien’ recognition contains several domains which are each highly variable. Every single B cell forms a unique immunoglobulin gene by picking from several short pre-existing DNA sequences. We also observe that later generations of immunoglobulins are more specific than the earlier generations, in the sense that they bind more tightly to invading microorganisms. Binding affinity to an invader is equivalent to recognition of that invader. And the better the immune system is able to recognize an intruder, the better it is able to clear it. The increased specificity is due to somatic mutations deliberately introduced in the genes of the immunoglobulins. A mechanism to rapidly induce mutations in immunoglobulin genes is present in the B cell genome. This mechanism ensures that the recognition pattern specified by the genes becomes increasingly specific for the intruder. This ability to recognize and defeat all potential microorganisms is characteristic of the immune systems of higher organisms, including humans. The genomes contain all the necessary biological information required to induce variation from within. A flexible genome is required to effectively ward off diseases and parasitic infections. B cells don’t wait for mutations to happen; they generate the necessary mutations themselves.

Darwin revisited

Previously, in part 2,1 I argued that organisms are equipped with flexible, highly adaptable, pluripotent, multipurpose genomes. Organisms are able to conquer the world through adaptive radiation of baranomes. But how do baranomes unleash information? Do organisms have to wait for selectable mutations to occur in order to rapidly invade and occupy novel ecological niches? Or were the baranomes of created kinds equipped with mechanisms to rapidly induce mutations, similar to the variation generated by B cells? Let’s turn to Darwin’s The Origin of Species, where we will find some clues. Darwin wrote quite extensively on variation, and in particular on the variation of feather patterns in pigeons:

‘Some facts in regard to the colouring of pigeons well deserve consideration. The rock-pigeon is of a slaty-blue, and has a white rump (the Indian sub-species, C. intermedia of Strickland, having it bluish); the tail has a terminal dark bar, with the bases of the outer feathers externally edged with white; the wings have two black bars; some semi-domestic breeds and some apparently truly wild breeds have, besides the two black bars, the wings chequered with black. These several marks do not occur together in any other species of the whole family. Now, in every one of the domestic breeds, taking thoroughly well-bred birds, all the above marks, even to the white edging of the outer tail-feathers, sometimes concur perfectly developed. Moreover, when two birds belonging to two distinct breeds are crossed, neither of which is blue or has any of the above specified marks, the mongrel offspring are very apt suddenly to acquire these characters; for instance, I crossed some uniformly white fantails with some uniformly black barbs, and they produced mottled brown and black birds; these I again crossed together, and one grandchild of the pure white fantail and pure black barb was of as beautiful a blue colour, with the white rump, double black wing-bar, and barred and white-edged tail-feathers, as any wild rock pigeon! We can understand these facts, on the well-known principle of reversion to the ancestral characters, if all the domestic breeds have descended from the rock-pigeon.’2

Darwin argues—and correctly so—that all domestic pigeon breeds have descended from the rock-pigeon. He even knew, as demonstrated above, how to breed the rock-pigeon from several distinct pigeon races following a breeding pattern. Darwin describes a breeding algorithm for pigeons, to obtain the ancestor to all pigeons! But does he also describe an algorithm for breeding turkeys from pigeons? No. Darwin doesn’t know such an algorithm. If he had found an algorithm for breeding ducks or magpies from pigeon genomes, he would have had solid evidence in favour of his proposal On The Origin of Species Through the Preservation of Favoured Races. His breeding experiments led him to discover ‘the principle of reversion to ancestral characters’, but contrary to common Darwinian wisdom, it is also the falsifying observation to his proposal for the origin of species. The observation that pigeons bring forth pigeons, and nothing else but pigeons, is not exactly the evidence needed to argue for the common descent of all birds. On the contrary! Darwin’s breeding experiments demonstrated that a pigeon is a pigeon is a pigeon. Characteristics and traits within single species of pigeons may vary tremendously, but he always started and ended with pigeons.

Breeding experiments have always shown, without exception, that novel and distinct bird species do not arrive through artificial selection. Even Darwin argues that there is no doubt that all varieties of ducks and rabbits have descended from the common wild duck and rabbit.3 From the variation Darwin observed in wild and domesticated populations, it does not follow that rabbits and ducks have some hypothetical common ancestor in a fuzzy distant past. Darwin observed inborn, innate variation that already existed in the genomes of the pigeons and it only had to be activated or expressed.

From the excerpt above, we may even get an impression of how it works. A genetic algorithm for making feathers (a feather program) is part of the pigeon’s genome and is present in every single cell. The feather program is present in billions of pigeon cells, but it is NOT active in all those cells. Feathers are only formed when the program is activated. The feather program is silent in cells where it should normally not operate. Activation of the feather program in the wrong cells may often be incompatible with life, but sometimes it may produce pigeons with (reversed) feathers on the feet. The program may be derepressed or activated through a mechanism that operates in the pigeon’s genome. Whether feathers appear on the feet or on the head, and whether they appear normal or reversed is merely a matter of activation and regulation of the feather program. But Darwin didn’t know about silent genomic programs or how they could become active. He didn’t know about gene regulation and molecular switches. Darwin did not know anything about genes and genomes.

Analogous variation

The idea that Darwin had been working on for over two decades prior to the publication of Origin, his idée fixe, was how organic change (i.e. variation) present in populations might explain how novel species came into being. Unchanging, stable species is not what Darwin had in mind. He pondered the riddles of variation; he thought about laws and principles associated with the process of variation and believed he could disclose them by the study of the formation of new breeds. Drawing from what he knew about pigeon breeding and equine varieties, Darwin describes some of his ideas about the ‘laws of variation’ in chapter five of Origin:

‘Distinct species present analogous variations; and a variety of one species often assumes some of the characters of an allied species, or reverts to some of the characters of an early progenitor. These propositions will be most readily understood by looking to our domestic races. The most distinct breeds of pigeons, in countries most widely apart, present sub-varieties with reversed feathers on the head and feathers on the feet, characters not possessed by the aboriginal rock-pigeon; these then are analogous variations in two or more distinct races.’4

Darwin describes that the exact same traits can appear in distinct breeds of pigeons and—importantly—these traits appeared independently in ‘countries most widely apart’. If several breeds arrive with the same characteristics independently, it is unlikely they do so because of chance. Rather, the pigeon genomes may activate or derepress the same feather program independently. The effect is that distinct breeds ‘in countries most widely apart’ acquire the same characteristics. Over and over the same traits appear in separated populations of organisms as the result of mutations ‘from within’. Animal breeders like exuberant patterns and rarities; that is exactly what they are looking for to select. Aberrant traits that are normally under stringent negative selection, as might be the case for the pigeon’s reversed feathers, may readily become visible as soon as the selective pressure is relieved; that is, when organisms are reared and fed in the protective environment of captivity. Darwin called the phenomenon of independent acquisition of the same traits analogous variation. It is a common phenomenon well known to breeders, and Darwin easily found more examples of analogous variation:

‘The frequent presence of fourteen or even sixteen tail-feathers in the pouter, may be considered as a variation representing the normal structure of another race, the fantail. I presume that no one will doubt that all such analogous variations are due to the several races of the pigeon having inherited from a common parent the same constitution and tendency to variation, when acted on by similar unknown influences. In the vegetable kingdom we have a case of analogous variation, in the enlarged stems, or roots as commonly called, of the Swedish turnip and Ruta baga [sic] plants which several botanists rank as varieties produced by cultivation from a common parent: if this be not so, the case will then be one of analogous variation in two so-called distinct species; and to these a third may be added, namely, the common turnip. According to the ordinary view of each species having been independently created, we should have to attribute this similarity in the enlarged stems of these three plants, not to the vera causa of community of descent, and a consequent tendency to vary in a like manner, but to three separate yet closely related acts of creation.’5

Analogous variation originates in the genome. Through rearrangement and/or transposition of DNA elements, previously silent (cryptic) traits can be activated. The underlying molecular mechanism can’t be merely random; if it were, then Darwin, and other breeders, would not have observed the expression of the same traits independently of each other. A more contemporary translation of analogous variation would be non-random (or: non-stochastic) variation, and it implies some sort of mechanism.

Reversions

In the excerpt above, Darwin also describes what he calls reversions. By this term he meant traits that are present in ancestors, then disappear in first generation offspring, and then reappear in subsequent generations. Darwin acknowledged that unknown laws of inheritance must exist, but still he talks about ‘the proportion of blood’. Reversions are easily explained as traits present on separate chromosomes, and the inheritance of such traits is best understood from Gregor Mendel’s inheritance laws. Through Mendel’s discovery of the genetic laws that underlie the inheritance of traits associated with chromosome segregation (a hallmark of sexual reproduction), Mendel gave us a quantum theory of inheritance. He found that traits are always inherited in well-defined and predictable proportions, and do not just come and go. Darwin’s ‘reversions’ are traits that reappear in later generations due to the inheritance of the same genes (alleles) from both parents.5

Darwin didn’t know about Mendel’s laws of inheritance, neither did he know about how variation is generated in genomes. What Darwin described in Origin, however, is that variation in offspring is a rule of biology. What Darwin described in isolated species (whether domesticated breeds or island-bound birds) was the result of a burst of abundant speciation resulting from multipurpose genomes. Variant breeds of pigeons are the phenotypes of a rearranged multipurpose pigeon genome. The Galápagos finches (with their distinct beaks and body sizes) are the phenotypes of a rearranged multipurpose finch genome. Where does the variation stem from in populations of Galápagos finches?

Darwin was well aware of the profound lack of knowledge on the origin of variation, and did not exclude mechanisms or laws to drive biological variation:

‘I have hitherto sometimes spoken as if the variations so common and multiform in organic beings under domestication, and in a lesser degree in those in a state of nature had been due to chance. This, of course, is a wholly incorrect expression, but it serves to acknowledge plainly our ignorance of the cause of each particular variation.’6

Since Darwin’s days, almost all corners of the living cell have been explored and our biological knowledge has expanded greatly. Through a vast library of data generated by new research in biology, we now have the answers to many questions of a biological nature that had puzzled Darwin. We may also have the answer to ‘the cause of each particular variation’, although we may not be aware of it (yet). That is not because it is hidden between billions of other books and hard to find. No, it is because of the Darwinian paradigm. The mechanism(s) that drive biological variations have been elucidated but are not yet recognized as such.

One of the findings of the new biology was that the DNA of most (if not all) organisms contains jumping genetic elements. The mainstream opinion is that these elements are the remnants of ancient invasions of RNA viruses. RNA viruses are a class of viruses that use RNA molecule(s) for information storage. Some of them, such as influenza and HIV, pose an increasing threat to human health. Are virus invasions responsible for all the beautiful intricate complexity of organic beings? Is a virus a creator? Most likely it is not. Otherwise why would we pump billions of research dollars into research to fight off viruses? Could it be that mainstream science is mistaken?

The RNA virus paradox

Here is one good reason for believing that mainstream science is indeed mistaken: the RNA virus paradox. It has been proposed that these RNA viruses have a long evolutionary history, appearing with, or perhaps before, the first cellular life forms.7 Molecular genetic analyses have demonstrated that genomes, including those of humans and primates, are riddled with ‘endogenous retroviruses’ (ERVs), which are currently explained as the remnants of ancient RNA virus-invasions. RNA virus origin can be estimated using homologous genes found in both ERVs and modern RNA virus families. By using the best estimates for rates of evolutionary change (i.e. nucleotide substitution) and assuming an approximate molecular clock,8,9 the families of RNA viruses found today ‘could only have appeared very recently, probably not more than about 50,000 years ago’.10 These data imply that present-day RNA viruses may have originated much more recently than our own species. The implication of a recent origin of RNA viruses and the presence of genomic ERVs poses an apparent paradox that has to be resolved. I will argue, in order to resolve the paradox, we should abstain from the mainstream idea that ERVs are remnants of ancient RNA virus invasions.

This intricate mechanism for transposition of ERVs seems to be irreducibly complex (and thus a sign of intelligent design) since all ERVs and RNA viruses use the same or similar genetic components.

Solving the RNA paradox can only be accomplished by asking questions. First, we have to ask ourselves, What do scientists mean when they refer to genetic elements as endogenous retroviruses (ERVs)? In addition, we have to ask, How do ERVs behave, and what—if any—are their functions? ERVs have been extensively studied in microorganisms, such as baker’s yeast (Saccharomices cerivisiae) and the common gut bacterium Escherichia coli. Most of our knowledge on the mechanisms of transposition of ERVs comes from those two organisms. In yeast, the ERV known as Ty is flanked by long terminal repeats and specifies two genes, gag and pol, which are similar to genes found in free operating RNA viruses. This is the main argument why scientists believe RNA viruses and ERVs are evolutionarily closely related. The long terminal repeats enable the ERV to insert into the host’s DNA. The transposition and integration is a stringently regulated process and seems to be target or site-specific.11,12 During the transpositions of an ERV, the host’s RNA polymerase II makes an RNA template, which is polyadenylated to become messenger RNA. The gag and pol mRNAs are translated and cleaved into several individual proteins. The gag gene specifies a polyprotein that is cleaved into three proteins, which form a capsid-like structure surrounding the ERV’s RNA. We may ask here: why is a capsid involved? It should be noted that single stranded RNA molecules are very sticky nucleotide polymers and the capsid may prevent the ERV from sticking at wrong places. The capsid may also be required to direct the ERV to the right spots in the genome. The pol polyprotein is cleaved into four enzymes: protease, reverse transcriptase, RNase and integrase. Protease cleaves the polyproteins into the individual proteins and then the RNA and proteins are packed into a retrovirus-like particle. Reverse transcriptase forms a single-stranded DNA molecule from the ERV RNA template, whereas RNase removes the RNA. The DNA is then circularized and the complementary DNA strand is synthesized to create a double-stranded, circular copy of the ERV, which is then integrated into a new site in the host’s genomic DNA by integrase’s activity. This intricate mechanism for transposition of ERVs seems to be irreducibly complex (and thus a sign of intelligent design) since all ERVs and RNA viruses use the same or similar genetic components.

Variation-inducing genetic elements (VIGEs).

What can the function, if any, of ERVs be? If we follow the mainstream opinion, ERVs integrated into the genomes a very long time ago as viral infections. Currently, ERVs are not particularly helpful. They merely hop around in the genome as selfish genetic elements that serve no function in particular. They are mainly upsetting the genome. Long ago, however, RNA viruses are alleged to have significantly contributed to evolution by helping to shape the genome.

It’s hard to imagine this story to be true, and not only because of the RNA virus paradox. Modern viruses usually do not integrate into the DNA of the germ line-cells; that is, the genes of an RNA virus don’t usually become a part of the heritable material of the infected host. If we obey the uniformitarian principle, we are allowed to argue: ‘What currently doesn’t happen didn’t happen a long time ago, either’. To answer the question raised above, we must start finding out more about some biological characteristics of a less complicated jumping genetic element, the so-called insertion-sequence (IS) element. IS elements are DNA transposons abundantly present in the genomes of bacteria. IS elements share an important characteristic with ERVs: transposition. Genome shuffling takes place in bacteria so frequently that we can hardly speak of a specific gene order. The shuffling of pre-existing genetic elements may unleash cryptic information instantly as the result of position effects. Shuffling seems to be an important mechanism to generate variation. But what is the mechanism for genome shuffling? The answer to this question comes unexpectedly from evolutionary experiments, in which genetic diversity (‘evolutionary change’) was determined between reproducing populations of E. coli. During the breeding experiment, which ran for two decades, it was observed that the number and location of IS (‘insertion sequence’) elements dramatically changed in evolving populations, whereas point mutations were not abundant.13After 10,000 generations of bacteria, the genomic changes were mostly due to duplication and transposition of IS elements. A straightforward conclusion would thus be that jumping genetic elements, such as the IS elements, were designed to deliberately generate variation—variation that might be useful to the organism. In 2004, Lenski, one of the co-authors of the studies, demonstrated that the IS elements indeed generate fitness-increasing mutations.14 In E. coli bacteria IS elements activate cryptic—or silent—catabolic operons: a set of genetic programs for food digestion. It has been reported that IS element transposition overcomes reproductive stress situations by activating cryptic operons, so that the organism can switch to another source of food. IS elements do so in a regulated manner, transposing at a higher rate in starving cells than in growing cells. In at least one case, IS elements activated a cryptic operon during starvation only if the substrate for that operon was present in the environment.15
It is clear that in Lenski’s experiments, IS elements did not evolve over night. Rather, the IS elements reside in the genome of the original strain. During the two decades of breeding, the IS elements duplicated and jumped from location to location. There was ample opportunity to shuffle genes and regulatory sequences, and plenty of time for the IS elements to integrate into genes or to simply redirect regulatory patterns of gene expression. Microorganisms may thus induce variation simply through shuffling the order of genes and put old genes in new contexts: variation through position effects that can be inherited and propagated in time. It’s hardly an exaggeration to state that jumping genetic elements specified by the bacterium’s genome generated the new phenotypes.

Transposition of IS elements is mostly characterized by local hopping, meaning that novel insertions are usually in the proximity of the previous insertion and may be a more-or-less random phenomenon; the site of integration isn’t sequence dependent. Bacteria have a restricted set of genes and they divide almost indefinitely. Therefore, sequence-dependent insertion and stringent regulation of transposition may not be required for IS-induced reshuffling of bacterial genomes; in a population of billions of microorganisms all possible chromosomal rearrangements may occur due to stochastic processes. In ‘higher’ organisms the order of genes in the chromosomes is more important, but there is no reason to exclude jumping genetic elements as a factor affecting the expression of genetic programs through position effects. Transposable elements may therefore be a class of variation-inducing genetic elements (VIGEs) in ‘higher’ organisms. Indeed, ERVs, LINEs and SINEs resemble IS elements in bacteria in that they are able to transpose. In fact, these elements may be responsible for a large part of the variability observed in higher organisms and may even be responsible for adaptive phenotypes. The genomic transposition of VIGEs is not just a random process. As observed for Ty elements in yeast, integration of all VIGEs may originally have been designed as site or sequence specific. It should be noted that VIGEs might qualify as redundant genetic elements, of which the control over translocation may have deteriorated over time.

VIGEs in humans

Mobile genetic elements make up a considerable part of the eukaryotic genome and have the ability to integrate into the genome at a new site within their cell of origin. Mobile genetic elements of several classes make up more than one third of the human genome.

Human endogenous retroviruses (ERVs) are, as with yeast ERVs, first transcribed into RNA molecules as if they were genuine coding genes. Each RNA is then transformed into a double stranded RNA-DNA hybrid through the action of reverse transcriptase, an enzyme specified by the retrotransposon itself. The hybrid molecule is then inserted back into the genome at an entirely different location. The result of this copy-paste mechanism is two identical copies at different locations in the genome. More than 300,000 sequences that classify as ERVs have been found in the human genome, which is about 8% of the entire human DNA.16

Figure 1. Variation-inducing genetic elements (VIGEs) are found throughout all biological domains, ranging from bacteria to mammals. In yeast, insects and mammals we observe similar designs. (Homologous sequences are indicated by the same colour).

Long terminal repeats retrotransposons (LTR retrotransposons) are transcribed into RNA and then reverse transcribed into a RNA-DNA hybrid and reinserted into the genome. LTRs and retroviruses are very similar in structure. Both contain gag and pol genes (figure 1), which encode a viral particle coat (GAG), reverse transcriptase (RT), ribonuclease H (RH) and integrase (IN). These genes provide proteins for the conversion of RNA into complementary DNA and facilitate insertion into the genome. Examples of LTR retrotransposons are human endogenous retroviruses (HERVs). Unlike RNA retroviruses, LTR retrotransposons lack envelope proteins that facilitate movements between cells.

Non-LTR retrotransposons, such as long interspersed elements (LINEs), are long stretches (4,000–6,000 nucleotides) of reverse transcribed RNA molecules. LINEs have two open reading frames: one encoding an endonuclease and reverse transcriptase, the other a nucleic acid binding protein (figure 1). There are approximately 900,000 LINEs in the human genome, i.e. about 21% of the entire human DNA. LINEs are found in the human genome in very high copy numbers (up to 250,000).17Short interspersed elements (SINEs) constitute another class of VIGEs that may use an RNA intermediate for transposition. SINEs do not specify their own reverse transcriptase and therefore they are retroposons by definition. They may be mobilized for transposition by using the enzymatic activity of LINEs. About one million SINEs make up another 11% of the human genome. They are found in all higher organisms, including plants, insects and mammals. The most common SINEs in humans are Alu elements. Alu elements are usually around 300 nucleotides long, and are made up of repeating units of only three nucleotides. Some Alu elements secondarily acquired the genes necessary to hop around in the genome, probably though recombination with LINEs. Others simply duplicate or delete by means of unequal crossovers during cell divisions. More than one million copies of Alu elements, often interspersed with each other, are found in the human genome, mostly in the non-coding sections. Many Alu-like elements, however, have been found in the introns of genes; others have been observed between genes in the part responsible for gene regulation and still others are located within the coding part of genes. In this way SINEs affect the expression of genes and induce variation. Alu elements are often mediators of unequal homologous recombinations and duplications.18

Figure 2. Schematic view of the central role VIGEs may play to generate variation, adaptations and speciation events. Lower part: VIGEs may directly modulate the output of (morpho)genetic algorithms due to position effects. Upper part: VIGEs that are located on different chromosomes may be the result of speciation events, because their homologous sequences facilitate chromosomal translocations and other major karyotype rearrangements.

Repetitive triplet sequences (RTSs) present in the coding regions of proteins are a class of VIGEs that cannot actively transpose. RTSs are usually found as an intrinsic part of the coding region of proteins. For instance, RTSs can be formed by a tract of glycine (GGC), proline (CCG), or alanine (GCC). Usually RTSs form a loop in the messenger (m)RNA that provides a docking site for chaperone molecules or proteins involved in the mRNA translation. RTSs may increase or decrease in length through slippery DNA polymerases during DNA replication.

Conclusions and outlook

Now that we have redefined ERVs as a specific class of VIGEs, which were present in the genomes from the day they were created, it is not difficult to see how RNA viruses came into being. RNA viruses have emerged from VIGEs. ERVs, LINEs and SINEs are the genetic ancestors of RNA viruses. Darwinists are wrong in promoting ERVs as remnants of invasions of RNA viruses; it is the other way around. In my opinion, this view is supported by several recent observations. RNA viruses contain functional genetic elements that help them to reproduce like a molecular parasite. Usually, an RNA virus contains only a handful of genes. Human Immunodeficiency virus (HIV), the agent that causes AIDS, contains only eight or nine genes. Where did these genes come from? An RNA world? From space? The most parsimonious answer is: the RNA viruses got their genes from their hosts.

These observations make it plausible that all RNA viruses have their origin in the genomes of living cells through recombination of host’s DNA elements

The Rous arcoma virus (RSV), which has the ability to cause tumours, has only 4 genes: gag, pol, env and src. In addition, the virus is flanked by a set of repeat sequences that facilitate integration and promote replication. Gag, pol and env are genes commonly present in ERVs. The src gene of RSV is a modified host-derived src gene that normally functions as a tyrosine kinase—a molecular regulator that can be switched on and off in order to control cell proliferation. In the virus, the regulator has been reduced to an on-switch only that induces uncontrolled cell proliferation. The src gene is not necessary for the survival of RSV, and RSV particles can be isolated that have only the gag, pol and env genes. These have perfectly normal life cycles, but do not cause tumours in their host. It is clear the virus picked up the src gene from the host. Why wouldn’t the whole vector be derived from the host? VIGEs may easily pick up genes or parts thereof as the result of an accidental polymerase II read-through. This will increase the genetic content of the VIGE because the gene located next to the VIGE will also be incorporated. An improper excision of VIGEs may also include extra genetic information. Imagine for instance HERV-K, a well-known human-specific endogenous retrovirus, transposing itself to a location in the genome where it sits next to the src gene. If in the next round of transposition a part of the src gene was accidentally added to the genes of HERV-K, it has already transformed into a fully formed RSV (see figure 3). It can be demonstrated that most RNA viruses are built of genetic information directly related to that of their hosts.

Figure 3. RNA viruses originate from VIGEs through the uptake of host genes. In the controlled and regulated context of the host DNA, genes and VIGEs are harmless. A combination of a few genes integrated in VIGEs may start an uncontrolled replication of VIGEs. In this way, VIGEs may take up genes that serve to form the virus envelope (to wrap up the RNA molecule derived from the VIGE) and genes that enable them to leave and re-enter host cells. Once VIGEs become full-blown shuttle vectors between hosts, they act as virulent, devastating and uncontrolled replicators. Hence, harmless VIGEs may degenerated into molecular parasites in a similar way normally harmless cells turn into tumors once they lose the power to control cell replication. VIGEs are on the basis of RNA viruses, not the other way around. The scheme outlined here shows how the Rous sarcoma virus (RSV) may have formed from a VIGE that integrated the env gene and part of the src gene (a proto-oncogene: for details see text).

The outer membranes of influenza viruses, for instance, are built of hemagglutinin and neuraminidase molecules. Neuraminidase is a protein that can also be found in the genomes of higher ‘host’ organisms, where it serves the function to modify glycopeptides and oligosaccharides. In humans, neuraminidase deficiency leads to neurodegenerative lysosomal storage disorders: sialidosis and galactosialidosis.19 Even so-called orphan genes, genes that are only found in viruses, can usually be found in the host genomes. Where? In VIGEs!

To become a shuttle-vector between organisms, all that is required is to have the right tools to penetrate and evade the defenses of the host cell. HIV, for instance, acquired part of the gene of the host’s defence system (the gp120 core) that binds to the human beta-chemokine receptor CCR5.20
These observations make it plausible that all RNA viruses have their origin in the genomes of living cells through recombination of host’s DNA elements (genes, promoters, enhancers). Every now and then such an ‘unfortunate’ recombination produces a molecular replicator: it is the birth of a new virus. Once the virus escapes the genome and acquires a way to re-enter cells, it has become a fully formed infectious agent. It has long been known that bacteria use genes acquired from bacteriophages—i.e. bacterial viruses that insert their DNA temporarily or even permanently into the genome of their host—to gain reproductive advantage in a particular environment. Indeed, work reaching back decades has shown that prophage (the integrated virus) genes are responsible for producing the primary toxins associated with diseases such as diphtheria, scarlet fever, food poisoning, botulism and cholera. Diseases are secondary entropy-facilitated phenomena.

Virologists usually explain the evolution of viruses as recombination: that is, a mixing of pre-existing viruses, a reshuffling and recombination of genes.21 In bacteria, viruses may therefore be recombined from plasmids carrying survival genes and/or transposable genetic elements, such as IS elements.

Discussion

Where did all the big, small and intermediate noses come from? Why are people tall, short, fat or slim? What makes morphogenetic programs explicit? The answer may be VIGEs. It may turn out that the created kinds were designed with baranomes that had an ability to induce variation from within. This radical view implies that the baranome of man may have been designed to contain only one morphogenetic algorithm for making a nose. But the program was implicit. The program was designed in such way that a VIGE easily integrated into it, becoming a part of it, hence making the program explicit. Most inheritable variation we observe within the human population may be due to VIGEs—Elements that affect morphogenetic and other programs of baranomes. It should be noted that a huge part of the genomic sequences are ‘redundant’ adaptors, spacers, duplicators, etc., which can be removed from the genome without major affects on reproductive success (fitness). In bacteria, VIGEs have been coined IS elements; in plants they are known as transposons; and in animals, they are called ERVs, LINEs, SINEs, and microsatellites. What these elements are particularly good at is inducing genomic variation. It is the copy number of VIGEs and their position in the genome that determine gene expression and the phenotype of the organism. Therefore, these transposable and repetitive elements should be renamed after their function: variation-inducing genetic elements. VIGEs explain the variations Darwin referred to as ‘due to chance’.

I will address the details of a few specific classes of VIGEs and argue why modern genomes are literally riddled with VIGEs in a future article. With the realization that RNA viruses have emerged from VIGEs the RNA paradox is solved. For many mainstream scientists this solution will be bothersome because VIGEs were frontloaded elements of the baranomes of created kinds and that implies a young age for their common ancestor and that all life is of recent origin.

Piltdown Man Territory. This is where Darwinism lives. It hoped for fruit flies to prove evolution but finally gave up on them. It trumpets victory concerning bacteria until further research proves otherwise. Darwinism depended upon vestigal organs until they proved to be useful. It claimed triumph concerning "junk DNA" until we discovered that said DNA had multiple functionality. Embryology was a hoped-for epic fail. Various missing links prove to be hoaxes and/or mistaken. Supposed human ancestors fall by the wayside. Like magicians, Darwinists ask you to watch what is in their hands while hiding what is really going on. Now we see that ERV is just another case of Darwinists promoting an idea that is so complex it will take the public a few years to catch on and realize that they have, once again, been had.

We'll snag a set of Creation-evolution headlines today - news taken from the world of science from the point of view of a normal brain not brainwashed by Darwinist propaganda. So this is one of several consecutive points I am going to make about evolution/Darwinism. Intelligent Design is not an argument from ignorance, it is an argument from evidence. We know designs come from a designer and we (operational scientists) have acknowledged design, wondered at design and copied design from the creations of God. While that is going on there are a set of priests preaching the religion of Darwin like Richard Dawkins, making preposterous statements as a matter of course. But there is no reason for you to believe them. Whereas there is an overwhelming stack of evidence for a created world:

Your DNA Repairman Is Handy as an Octopus 03/27/2011
March 27, 2011 — Some 10 times a day in a given cell, your DNA breaks on both strands. This is an emergency. Unless repaired quickly, serious diseases, like cancer, can develop. But no fear: the first responder is an octopus-shaped protein complex that rushes to the rescue, wraps around the damaged site, and brings in all the parts needed to fix it. Such mechanical acrobatics in the cell are only now coming into clearer focus.

A press release at the Scripps Research Institute described this amazing repair system called MRN with its three protein subunits (Mre11-Rad50-Nbs1; for illustration, see Science Daily). The researchers wanted to find out how MRN “can repair DNA in a number of different, and tricky, ways that seem impossible for ‘standard issue’ proteins to do,” the press release said. These proteins are not static balls of amino acids; they have dynamic, interactive, moving parts. The motor in the complex, Rad50, “is a surprisingly flexible protein that can change shape and even rotate depending on the task at hand.” Here’s the octopus part of the story:

The scientists say that the parts of the complex, when imagined together as a whole unit, resemble an octopus: the head consists of the repair machinery (the Rad50 motor and the Mre11 protein, which is an enzyme that can break bonds between nucleic acids) and the octopus arms are made up of Nbs1 which can grab the molecules needed to help the machinery mend the strands.

They saw “a lot of big movement” in the repair operation. First, the complex has to assess the damage:

When MRN senses a break, it activates an alarm telling the cell to shut down division until repairs are made. Then, it binds to ATP (an energy source) and repairs DNA in three different ways, depending on whether two ends of strands need to be joined together or if DNA sequences need to be replicated. “The same complex has to decide the extent of damage and be able to do multiple things,” [John] Tainer [Scripps Research Professor] said. “The mystery was how it can do it all.”

Tainer described how some of the parts interact: “Rad50 is like a rope that can pull. It appears to be a dynamic system of communicating with other molecules,” he said. It uses ATP, the energy currency of all life, to get into shape: “When not bound to ATP, Rad50 is flexible and floppy, but bound to ATP, Rad50 snaps into a ring that presumably closes around DNA in order to repair it.”

How a set of proteins can sense damage, migrate to a repair site, assess the extent of the break and select the correct repair option, link up to other tools, bring in parts, and put everything back together again is surely one of the wonders of biology coming to light with new observing techniques. The research was funded by the National Cancer Institute, the National Institutes of Health, and the Department of Energy, and published in Nature Structural and Molecular Biology,1 March 27, 2011.

The abstract did not mention evolution except to say that the parts are “conserved” (unevolved) across all living things. The researchers studied this complex in yeast and archaea – among the simplest of microbes. A different paper in a different journal studied another wonder of the cell without mentioning evolution (except to mention “evolutionarily conserved proteins”). In PLoS Biology,2 Linton Traub [U of Pittsburgh] discussed how proteins coat vesicles that dive into the cell membrane to bring in substances from outside the cell.

In “Regarding the Amazing Choreography of Clathrin Coats,” Traub described clathrin-mediated endocytosis (see 10/17/2003, 05/15/2005, 11/04/2005, 02/02/2010, bullet 3). He started with a recounting of the discovery of clathrin, a three-spoke protein that wraps around vesicles like a geodesic dome, and then described some of the latest findings: “Yet, what we have learned over the past decade is that the assembly of these core components is augmented and precisely regulated at vesicle bud sites by an abundance of additional proteins” – at least 40, at last count. The realization that so many players are involved in this critical import process “puts to rest the parsimonious assertion that the complexity of clathrin coat assembly is wildly overstated,” he said. 1.

The facts themselves scream intelligent design so clearly, any additional comments would be superfluous. Was evolution useful to any of this research? Does an octopus need a hot air balloon? Next headline on:Cell Biology • Genetics • Intelligent Design • Amazing Facts

Neurons Know What to Do 03/27/2011
March 27, 2011 — Neurons are among the most vital cells in the body: after all, your brain is largely composed of neurons. Neurons are transmission lines of information that keep a body in touch with itself and the world. None of the other body organs would work without neurons. The increasingly powerful tools of microscopy are allowing neuroscientists to figure out how they develop and operate.

Motors in a network within a network: In an article entitled “Motors on a mission,” PhysOrg described how the human nervous system, a vast network of billions of neurons, can be conceived as a network of networks: “Within each neuron is a microscopic network of its own, a complex system of signal transmissions. Proteins receive signals at the cell’s dendrite and transmit them at the axon at the other end, passing the impulses from one neuron to another and allowing human beings to think, perceive and move.”
The network within a single neuron is a system of microtubules. On these cellular highways, myosin motors carry the molecules of signal transduction from place to place. Proteins needed by the axons and dendrites are made in the neuron and packaged into bubble-like vesicles, which are carried by various types of myosins. “Neither the two proteins themselves nor the microtubules know where the proteins should end up,” (after all, they are blind), “so a mix of dendritic and axonal proteins will go both ways, to the dendrite and to the axon,” the article said.
When a protein ends up at the wrong end, other myosins round up wayward vesicles and turn them back. Myosin Va acts as a filter at the axons, allowing axon-bound vesicles in but carrying dendrite-bound packages out. Axonal proteins that end up in a dendrite are placed on the surface of the cell, where Myosin VI plucks them off and carries them to the axon. Myosin VI also helps axonal proteins find the axon in the first place. How these molecular machines recognize which is which was not explained.

Hearing in a crowded room: How do neurons get their information to the right target in the intensely crowded environment of the brain? It’s like shouting to a friend in a crowded room. Another article on PhysOrg described how they do it, with the headline, “‘Can you hear me now?’ Researchers detail how neurons decide how to transmit information.”
The article described how researchers at Carnegie Mellon and U of Pittsburgh are finding out the mechanisms neurons use to communicate. Neurons can fire separately or together when communicating, like when you shout alone to a friend, or get some friends to shout together. One researcher explained, “Neurons face a universal communications conundrum. They can speak together and be heard far and wide, or they can speak individually and say more. Both are important. We wanted to find out how neurons choose between these strategies.” They found that “the brain had a clever strategy for ensuring that the neurons’ message was being heard.”

Over the short time scale of a few milliseconds, the brain engaged its inhibitory circuitry to make the neurons fire in synchrony. This simultaneous, correlated firing creates a loud, but simple, signal. The effect was much like a crowd at a sporting event chanting, “Let’s go team!” Over short time intervals, individual neurons produced the same short message, increasing the effectiveness with which activity was transmitted to other brain areas. The researchers say that in both human and neuronal communication alike, this collective communication works well for simple messages, but not for longer or more complex messages that contain more intricate information.
The neurons studied used longer timescales (around one second) to convey these more complex concepts. Over longer time intervals, the inhibitory circuitry generated a form of competition between neurons, so that the more strongly activated neurons silenced the activity of weakly activated neurons, enhancing the differences in their firing rates and making their activity less correlated. Each neuron was able to communicate a different piece of information about the stimulus without being drowned out by the chatter of competing neurons. It would be like being in a group where each person spoke in turn. The room would be much quieter than a sports arena and the immediate audience would be able to listen and learn much more complex information. (Source: Carnegie Mellon University).

This effective two-strategy style gave the researchers ideas about designing man-made communication networks around the same principles.

Mapping the brain: Researchers at the Max Planck Florida Institute spent five years devising methods to map the cerebral cortex, and find how the neurons fit together. PhysOrg said they identified nine cell types in rat brains, and “were able to quantify the number of neurons per type, their locations within the cortical column and their functional responses to two behavioral states....” It required terabytes of information for each neuron. The cerebral cortex in humans is the “largest and most complex area of the brain, whose functions include sensory perception, motor control, and cognition.”

Bilingual neurons: Neurons used to be classified by the kind of chemical messages, called neurotransmitters, they conveyed. Now, according to Science Daily, two teams have found neurons that speak two languages; they can use one neurotransmitter at slow speeds, and another at high speeds. This mechanism, called co-transmission, “allows a single neuron to use two different methods of communication to exchange information.” Researchers at the University of Montreal found that neurons that typically use dopamine to communicate can also use glutamate for signals needing faster transmission. Researchers at Douglas Mental Health University Institute also found that neurons that typically use serotonin used to transmit “information for controlling mood, aggression, impulsivity and food intake” are also capable of transmitting “acetylcholine, an important messenger for motor skills and memory.”
A messenger, however, is only as good as the message it carries. Serotonin, for instance, does not mean “control aggression” in and of itself. There has to be a convention, a code, an agreement between parties, for something to signal something else and produce a response.

Outside/Inside Learning: An animal needs to gather information from the outside world and store it in memory. How this is accomplished was described in another article on PhysOrg about research done by a Swiss team. “It is well established that environmental enrichment, providing animals with rich sensory, motor, and social stimulation, produces both dramatic increases in the number of synapses in the brain and enhanced learning,” the article began. This means that outside information produces structural changes on the inside.
New techniques are allowing scientists to watch the brain form new synapses (the junctions between neurons) in response to environmental signals. “Remarkably, both the disassembly of pre-existing synapses and the assembly of new synapses were necessary to enhance learning and memory upon environmental enrichment,” they found, adding, “We have shown that circuit remodeling and synaptogenesis processes in the adult have important roles in learning and memory.” A protein named beta-Adducin is apparently critically important in the formation of new synapses. For more on synapses, see 12/23/2010.

How did these complex systems come to be? Another article on PhysOrg titled “The evolution of brain wiring: Navigating to the neocortex” proposed to answer that question from a Darwinian viewpoint. The lead researcher in Paris wanted to know how axons find their targets. “The research, published by Cell Press in the March 24 issue of the journal Neuron, reveals a surprising new evolutionary scenario that may help to explain how subtle changes in the migration of ‘guidepost’ neurons underlie major differences in brain connectivity between mammals and nonmammalian vertebrates.”

Identifying differences, though, does not establish that one group evolved from the other. Dr. Sonia Garel admitted, “What controls the differential path-finding of thalamic axons in mammals versus nonmammalian vertebrates and how these essential projections have evolved remains unknown,” but then suggested that a protein named Slit2 acts like a molecular switch for guiding developing neurons to their target areas in the brain. Since Slit2 positions neurons, she thought that minor differences in the resulting positions provides “a novel framework to understand the shaping and evolution of a novel and major brain projection” in different groups of animals. Why, that might even affect brain connectivity. A brain permitting her to reason as a neuroscientist could not be far behind: “Since an increase in cell migration has participated in the morphogenesis of the neocortex itself, these novel findings reveal that cell migration can be considered as a general player in the evolutionary changes that led to the emergence of the mammalian brain.”

Oh, barf. There she goes again: scenarios, frameworks for understanding, participants and general players (see personification) and emergence, amply seasoned with maybes and perhaps. You’re a scientist, aren’t you? Think, don’t imagine! Prove your case with facts and evidence. If imagining scenarios is the new scientific game, we can think of many more that are more entertaining.
Aside from that brief episode of Malice in Blunderland, this was an amazing series of articles. Most of them avoided the temptation to insert evolutionary speculation into their work. Think about it; how a complex set of mechanical processes – motors, chemical signals, guideposts, filters, networks, transmission rules – all converge into the brain of a neuroscientist looking into his or her own head and reasoning about it is astonishing. In the history of intellectual ideas prior to the invention of the electron microscope and other tools that allow us to see neurons and watch these processes, who could have dreamed such complexity underlies human thought? We should stand in humble awe at the hardware and software given to our minds and souls to use (02/11/2011, 03/05/2011).
Incidentally, a human brain said to be 2,500 years old was found in remarkably fresh condition, cerebral folds and all, in a waterlogged pit, reported Live Science. Aside from the issue that such fragile tissue – usually the first to decay – could survive degradation for so long, this illustrates that it takes more than a brain to think. You might get a buried car to work again with enough repairs, but the mind or soul – whatever you want to call it – that operated this brain is long gone, even if they could hotwire its neurons once again. It takes most of a whole body to run a brain, and a brain to run a body.
Have you ever looked at an X-ray or MRI image of your own brain? There’s more going on inside than you can possibly imagine (see also 03/24/2011, 12/06/2010, 11/19/2010) We all have comparable physical equipment; some choose to use it more wisely than others.

We Are Filled with Viruses 03/26/2011
March 26, 2011 — Viruses have a bad connotation. We immediately think of the ones that cause disease: “I’ve got a virus,” you say when feeling under the weather. Actually, you have trillions of them all the time, even in the best of health. A single gram of stool sample can have 10 billion of them! What does that mean? Scientists are only beginning to find out.

One thing it means is that they can’t be all bad. Elizabeth Pennisi reported in Science this week about work at the University of British Columbia and Washington University to explore the human virome.1 She began her report,

In the past decade, scientists have come to appreciate the vast bacterial world inside the human body. They have learned that it plays a role in regulating the energy we take in from food, primes the immune system, and performs a variety of other functions that help maintain our health. Now, researchers are gaining similar respect for the viruses we carry around.

Bacteria have been easier to count than the tiny viruses. Many of our internal viruses are bacteriophages that invade and kill bacteria. This suggests they play a role in keeping the brakes on bacterial infections. “For every bacterium in our body, there’s probably 100 phages,” Pennisi wrote. The number of virus species identified in stool samples of healthy adults varied from 52 to 2773. “The viromes varied significantly from one individual to the next; they were even more diverse than the bacterial communities within the same individuals,” Pennisi reported. “But each person’s viral community remained stable over the course of the year.” That is, unless they go on a different diet or eating regimen; then the viromes change. But people who eat the same foods tend to converge on virus profiles. Researchers also found that infants with fevers had more viruses than healthy infants.

We are full of viruses, in other words, but we don’t know what they all do. This is “a true frontier” of research, with much to learn. “Ultimately, those viruses are incredibly important in driving what’s going on” one scientist from the University of British Columbia said. It’s not enough to know your bacteria; you have to know the viruses that interact with them. 1. Elizabeth Pennisi, “Microbiology: Going Viral: Exploring the Role Of Viruses in Our Bodies,” Science, 25 March 2011: Vol. 331 no. 6024 p. 1513, DOI: 10.1126/science.331.6024.1513.

It’s always been intriguing that viruses look incredibly well designed. Some bacteriophages look like lunar landing capsules, legs and all. Scientists have learned that some viruses have shells like hard plastic (05/07/2004) and pack their DNA into their capsids with motors generating remarkable force, in an orderly manner (03/20/2007, 12/30/2008). They are also extremely effective in finding their target cells, inserting their DNA, and commandeering the genetic machinery to make copies of themselves.
Evolutionists don’t know what to do with viruses. They are not considered transitional forms between molecules and life. Intelligent design would describe their design and predict that they have functions, but would be at a loss to explain harmful viruses. It takes Biblical creation to explain that they were probably designed for good originally, but some became harmful because of the Fall due to sin. The analogy might be to a science fiction movie where robotic servants went berserk, or to the broom of the sorcerer’s apprentice that multiplied and could not be stopped. Sometimes a single mutation can turn a beneficial bacterium into a disease-causing terror; the same could be true with viruses.
Maybe they were intended to be regulators of bacteria. Maybe they were designed to convey information to the body about new environments, and were equipped to copy themselves to spread the word so that the body could be prepared. Who knows? This is, after all, a frontier of research. For philosophers, it’s noteworthy that we are stumbling onto a reality right around us – right within us – about which we have been largely oblivious, with the potential to dramatically change our understanding of nature.
Given that an athlete running the high hurdles in the peak of health is carrying around trillions of viruses, intuition suggests that most of what they do for us is good. The scientific research appears poised to find many beneficial functions for our viral passengers. It happened with bacteria; it took society a long time to change the emotional response from “germs... uggh!” with the householder running to get the antibacterial spray, to an appreciation of the many good things bacteria do for us. Now we look differently upon our bacterial passengers. We have learned they outnumber our own cells, and are learning that our viral passengers outnumber the bacteria 100 to one. Expect amazing things to be discovered about these tiny, mysterious machines. Next headline on:Cell Biology • Genetics • Human Body • Health

Four years ago, biologists held a symposium to find macroevolution, so that they could battle the “antievolution community”. So what did they come up with? Get ready to laugh: revisit the 03/28/2007 entry.

What article? No article here, just another hunk of YEC fiction. So it's possible, with a lot of fiddling-with-terms, to explain endogenous retroviruses in terms of YECism. So what? I'm sure it would be possible to explain the Fukushima power plant crisis in terms of caloric theory, but why bother? Caloric theory is wrong, and so is YEC.

Why is it, do you suppose, that Darwinist commenters ignore the evidence that life cannot form on it's own, that matter cannot form on it's own, that information only comes from intelligent sources and that the sedimentary rocks do not support uniformitarianism and the fossil record is not a sequential story of evolution but rather a testament to a world-changing flood event?

Because all of those claims are false. Thus, any theory based on those claims is also false.

Things for which both YEC and evolutionary theory can produce sensible explanations:

[long list of items redacted for space]

Things for which YEC can't produce a sensible explanation:

* The no-young-isotopes phenomenon* Fossiliferous strata in Large Igneous Provinces* Age-specific trace molecules in crude oil* Fossils in marble and slate* Weathered, scavenged, and broken fossils* Ecological ghosts* Index features such as the K-T clay layer* The sequential nature of the fossil record* The fact that certain types of organisms are never found together in the fossil record, despite being similar in shape, size, lifestyle, and habitat* The fact that certain sets of organisms are always found together in the fossil record, despite no similarity in shape or size* Multiple fossil horizons stacked atop one another, containing multiple nesting grounds* Subterranean plutonic intrusions in between fossiliferous strata.* Genetic markers such as the Vitamin C gene* Transitional forms such as Archaeopteryx, Beipiaosaurus,Diarthrognathus, Sphecomyrma, and others far too numerous to mention* The distribution patterns of living organisms* The presence of atavisms such as legs on whales and extra toes on horses* The presence of vestigial traits such as teeth-buds in chicks and eggshells in marsupials

(Note that this is only a partial list)

Things for which conventional geology and evolutionary theory can't produce a sensible explanation:

Despite all the copypasted verbiage in this blog post, Radar (and YECs in general) is short an explanation for the positioning of ERVs in humans and chimps. Evolution still explains it perfectly, and YEC is still saddled with astonishing odds against this positioning, which it can not explain.

A person with an open mind would concede this issue, but no doubt, Radar, you will shower others with derision while evading the issue.

I had a look. You pointing at that bit of propaganda puts the lie to your claim that you like science with evidence included. It's childish and devoid of any scientific discussion. Please do better in future if you wish to be respected.

"Things for which conventional geology and evolutionary theory can't produce a sensible explanation:"

Why do men have nipples? Ha. Put that in your pipe and smoke it tough guy.

"The fossil record is not compatible with the biblical flood, let alone a testament to it."

It doesn't have to be in order for the flood to be true. If we had concrete scientific evidence of miracles they wouldn't be miracles would they? If for God to exist He would have to fit in with accord to scientific laws and humanistic laws of logic He in essence wouldn't be God.

"It doesn't have to be in order for the flood to be true. If we had concrete scientific evidence of miracles they wouldn't be miracles would they?"

Do I understand correctly that you consider the Flood to be a miracle? So when Radar claims that there's scientific evidence for the Flood he's wrong?That said; if everything God does can be considered a miracle, should creationists like Radar even look for scientific evidence?

"Why do men have nipples? Ha. Put that in your pipe and smoke it tough guy."

Sorry, I don't smoke. But I can answer your question. (What, you really thought I couldn't? :-) ) It's well known that the female form is the default for mammals. A developing mammal embryo is turned into a male by the action of regulator genes on the Y chromosome. But several traces of the original female form remain, such as the nipples.

There's even at least one mammal species, a type of bat, in which the male routinely develops functioning mammae, presumably to help nurse the young.

"If we had concrete scientific evidence of miracles they wouldn't be miracles would they? If for God to exist He would have to fit in with accord to scientific laws and humanistic laws of logic He in essence wouldn't be God."

Miracles may not require scientific evidence as to how they occurred - they are supposed to "magic" after all.

But we should definitely have scientific evidence that they occurred, which in the case of the biblical flood, we don't. The fossil record utterly contradicts it, as do tree ring and ice core chronologies that are apparently unaffected by the flood etc.

We have observable evidence that tells us no global flood took place 4,000 years ago, and we have an ancient religious text that some believe tells us it did. Your response? "It's magic and God is above these things."

"If for God to exist He would have to fit in with accord to scientific laws and humanistic laws of logic He in essence wouldn't be God."

This misses the point by a mile. If God exists and all of nature (including us) is his creation, then scientific observations, laws of logic etc. would naturally perfectly tie in with God. It would be impossible for nature to show anything that clashes with God, because nature was created ("written") by God.

Nature, too, is God's word, and Christians can not dismiss it. Christians have more certainty that nature exists, on the basis of their own observations, than that the fallible men who wrote the Bible got everything right, given their limited knowledge of the time.

Or, wait... is this what you call "levity"? In that case you're right: please don't attempt levity again. Not your forte.

BTW, Jon Woolf, thanks for the (partial) list that YEC can't account for and that directly falsify it. I was amused by Radar's weak attempt to "explain" the fossil record by referring to the ice age that he claims followed it. A simple follow-up question and he's already reached the end of his wits on that issue.

"Or, wait... is this what you call "levity"? In that case you're right: please don't attempt levity again. Not your forte."

I was referring to my nipples remark, which apparently all the geeks are taking way too seriously.

"We have observable evidence that tells us no global flood took place 4,000 years ago,"

a lack of evidence that a flood took place is not the same as having evidence that no flood took place.

"If God exists and all of nature (including us) is his creation, then scientific observations, laws of logic etc. would naturally perfectly tie in with God. It would be impossible for nature to show anything that clashes with God, because nature was created ("written") by God."

"a lack of evidence that a flood took place is not the same as having evidence that no flood took place."

Er, that's not what it said. It's not a lack of evidence for a global flood, it's evidence that there was no global flood during that time. Positive evidence that there was no flood about 4,000 years ago (or at any other time in the last 10,000 years or so), not lack of positive evidence that there was a flood.

"Nothing in nature clashes with God so I fail to see your point."

Nothing in nature clashes with the possible existence of God (since the existence of God is not scientifically falsifiable).

Some things in nature do clash with a literal interpretation of some parts of the Bible. And since nature was also "written" by God, then which trumps which?

So you have no explanation for the identical positioning of ERVs in chimps and humans - none at all. Instead you paste a lengthy article that I very much doubt you yourself even understand and that doesn't begin to address the issue, and you accuse others of lying instead of addressing their arguments.

If you disagree, how about you explain in your own words how you think the article disproves the identical positioning of ERVs in chimps and humans as evidence for common descent? Barring that, we'll have to assume that you're just trying to impress readers with yet another lengthy science article that you don't understand.

Evidence that a global flood didn't take place approx. 4,000 years ago:

Tree ring chronologies going back further than that (to about 11,000 years ago), with no sign of such a catastrophic event. If a global flood had occurred 4,000 years ago, there would have been a trace of it in the tree ring records.

Ice core layers going back hundreds of thousands of years, again with no sign of such a catastrophic event. If a global flood had occurred 4,000 years ago, ice core layers would show a drastic change in consistency about 4,000 layers down (actually - the ice core layers would simply end there).

Sequential layering of fossils in accordance with the theory of evolution (including intermediate layers that would have taken a long time to form) in the fossil record, which would have been impossible if these layers had formed in a year or so 4,000 years ago.

Looking forward to your sweaty derision and nervous, blustery evasions... in lieu of a well-reasoned argument against the evidence.

"I also love how, for hb, everything seems to boil down to "god works in mysterious ways"."

You should love it, because its simple logic. You should try some. If you're going to examine the possibility of the existence of an infinitely powerful, eternal, supernatural being than you have to concede in your examination that He would be far enough above you that there would be lots you don't understand about Him. That is pure simple logic. So using the fact that a supernatural being doesn't fit nice and neatly into a finite natural framework as an argument against His existence is simply ridiculous.

But I love the way you have no actual argument against the existence of God but instead mock those who believe. Ironically, guys like Jon whom you seem to keep a poster of on your wall also claim to be theist. Sorry if that screws up your man crush.

Sorry, Radar, it doesn't work that way. We don't have to prove that it didn't happen. You have to prove that it did. There's a very long list of evidence that seems inconsistent with a global flood. I gave a few examples up above. It's on you now to demonstrate how this evidence can be explained by a global flood.

highboy: Ironically, guys like Jon whom you seem to keep a poster of on your wall also claim to be theist.

Er, no. Maybe you got that impression, but you were mistaken. I'm a mu-theist: I think the question 'do gods exist' has no meaning.

Oh and hb, I read this on the internet somewhere but if, as you say, your god is "an infinitely powerful, eternal, supernatural being", why is he so jealous (see the 10 commandments), arrogant and petty that he would choose to torture people for eternity if they won't be his cheerleader? The logic in all of this, to me, says that ALL religions are man made. And not how you apparently believe, i.e. that every other religion on earth, aside from yours, is man made. Logic, I'm afraid, is just not on your side in this debate.

The ultimate determinate in the struggle now going on for the world will not be bombs and rockets but a test of wills and ideas – a trial of spiritual resolve; the values we hold, the beliefs we cherish and the ideas to which we are dedicated — Ronald Reagan
